The Legal Framework of the Authority of Res Judicata: A Comparative Analytical Study

Abstract

This research examines the principle of res judicata (the authority of a settled matter) as a substantive rule, whereby judicial rulings possess binding authority regarding the issues they have adjudicated. This authority attaches to the judgment immediately upon its issuance, and the court may invoke it sua sponte at any stage of the proceedings. Res judicata is a fundamental, well-established judicial principle aimed at achieving legal stability and safeguarding the legal positions of litigants following the issuance of definitive judgments. The study highlights the distinction between the force of a judgment and its binding authority (res judicata); the latter specifically precludes the re-litigation of the same dispute once all avenues of appeal have been exhausted. Furthermore, the researcher analyzes the procedural nature of the plea of res judicata and its relationship to public policy—a connection that empowers the court to raise the issue sua sponte in specific circumstances. The study also reviews relevant legislation and judicial trends to determine the extent to which the scope of res judicata in civil judgments is broadened or restricted. The findings reveal a convergence between Islamic Sharia and positive law regarding the necessity of finality to resolve disputes and prevent conflicting judgments. Finally, the study offers recommendations for amending certain legislative provisions to refine the exceptions to res judicata, thereby ensuring a balance between the fairness of the judgment and the definitive resolution of the dispute.
